METHOD OF MANUFACTURING SOLID-STATE IMAGING DEVICE AND SOLID-STATE IMAGING DEVICE |
摘要 |
According to one embodiment, the method of manufacturing a solid-state imaging device includes: forming a plurality of photoelectric conversion elements by two-dimensionally arranging semiconductor areas of a second conductivity type at a semiconductor layer of a first conductivity type in a matrix pattern; forming the photoelectric conversion elements in a rectangular shape in plan view, the photoelectric conversion elements being formed by forming a grid-like trench in plan view so as to partition the semiconductor layer; forming the photoelectric conversion element formed into the rectangular shape in plan view into a convex polygonal shape in plan view whose number of corners is larger than the number of corners of a rectangular; and forming an element isolation area including a light shielding member at a trench coated with an insulating film after coating an inner peripheral surface of the trench with the insulating film. |

1. A method of manufacturing a solid-state imaging device, comprising:
forming a plurality of photoelectric conversion elements by two-dimensionally arranging semiconductor areas of a second conductivity type at a semiconductor layer of a first conductivity type in a matrix pattern; forming the photoelectric conversion elements in a rectangular shape in plan view, the photoelectric conversion elements being formed by forming a grid-like trench in plan view so as to partition the semiconductor layer; forming the photoelectric conversion element formed into the rectangular shape in plan view into a convex polygonal shape in plan view whose number of corners is larger than the number of corners of a rectangular; and forming an element isolation area including a light shielding member at a trench coated with an insulating film after coating an inner peripheral surface of the trench with the insulating film. |
